To all-whom it may concern:

Be it known; that I, ALBERT A. llNRUH, a

citizen. of the United States,-"residing ;at,

Portland, .in, the county of Multnomahand Stateof Oregon, have invented certain new and useful Improvements in fAntislipping Devices for Shoes; and I do ,declare the following to be ,a full, clear, and exact description of the invention, such as will enable others skilled in the art-towhich'it appertains to make and useithesame. 7

My invention has for its principaljobject to provide an extremely simple and inexpensive, yet a highly efficient-and durable anti-- slipping device or toe calk designed "prif-w marily for use upon athletic shoes of all sorts although it could well be employed on other shoes as an ice creeper.

Another object of the invention is to provide the calk with a resilient tongue for cleaning it of dirt and the like with which it would otherwise be clogged; and in this connection a still further object is to secure the cleaning tongue in place in a novel manner so that it may be readily removed whenever necessary.

WVith the foregoing general objects in view, the invention resides in the novel features of construction and unique combinations of parts to be hereinafter fully described and claimed, the descriptive matter being supplemented by the accompanying drawings which form a part of this specification and in which:

Figure 1 is a perspective view of the in vention applied to a shoe;

Fig. 2 is a longitudinal section of the de- .vice;

Fig. 3 is a perspective'view of the invention detached from the shoe;

Fig. 4 is a. perspective view of the shaped calk; and

Fig. 5 is a similar view of the calk cleaning tongue.

In the drawings above briefly described, the numeral 1 designates a U-shaped calk formed of a single piece of metal and having lateral ears 2 on its upper edge for securing it to the shoe sole, the lower edge of said calk being sharpened at 3 to penetrate the earth; and this edge preferably inclines upwardly and rearwardly as shown most clearly in Fig. 2. The ends of the U-shaped calk 1 are rigidly connected by a transverse rod 4,

v grally therewith and wardly to simultaneous Specification of Letters' 'late nt. a n 'dqmy 30,1915; A lication filed lia'r'chl, 191s. ser1a1m.

and spaced inwardly red, I the upp 15 ed e or any other'isuitable'portion ofthe ,cal ,is provided with. a pair: of internal lugs 5 which are preferably: formed"intek-J shown in the drawings.

spring metal tongue 6 isdisposed between the arms of theicalk lliand isshapedto 'en:--. 1

tongu is bent upwardly? and; forwardlyat 7 around the rod 4 and then e'xtends forwardly a suitable distance lfrfom= this rod to form. a spring catch 8 underlying the lugs 5 to anchor the rear end of the tongue, this end being bent upwardly to form a flange vent into. position as r 0 ,A calk cleaningmember'in the form of-a- 9 to engage the front edges of said lugs so that rearward movement of the tongue is prevented. Outward movement of thefront end of tongue 6 is prevented by a lug 10.

preferably bent inwardly from the lower edge of the calk 1, and; although only one of,

these lugs is shown, it will be obvious that any preferred number could be employed. Furthermore, it may be expedient in some cases to provide other means for reventing excessive outward movement of the tongue.

In use, the tongue 6 yields upwardly each time the foot is lowered upon the ground thus exposing the calk 1 for anti-slipping engagement with the earth or ice. The moment the foot is raised, however, the'resilie ency of the tongue 6 returns'the latter to its l'owenn'ost position and thus. any matter clog the calk, will be discharged' from the which wouldotherwise accumulate in and latter so that it is kept clean and eflicient at all times. Whenever it is necessary remove the tongue 6, the entire calk must be 7 V detached but itis then a simple "matterto depress the spring catch 8 so that its flange 9 will disengage the lugs 5, after which the entire tongue may be shifted rear- 10 and the rod 4.

pensive yet it will obvious that it will be highly eflicient and durable either as an athletic calk or as an ice creeper.- Furthermore, although the calk is shown only on the toe of the shoe sole, it will be understood that it could also be employed on the heel if On account of its adydisengage the lug I The device is extremely simple and inexvantages, the construction shown and described is preferably employed, but within the -scope of the invention as claimed, 'numerous minor changes maywellbe made.

I claim:

1. An anti-slipping device for shoes comprising a U-shaped oalk, means for securing said calk to the shoe sole, an upwardly yielding Cleaning member between the arms of said calk, and a releasable spring catch for holding said cleaning member in place.

2. A structure as specifiedin-olaiin 1, said cleaning member being constructed oi-spring metal and said oatch'being formed of a portion of said member.

3. An anti s'lipping device forshoes comprising a U-shaped cal'k, means for securmg said call: to the shoe sole, arod extending transversely between the ends of leasable 'springcatch, said catch engaging said lugs'to (anchor one end'of said'tongue, and means for preventing outward "movement of the other end of said tongue beyond said calk.

AL An anti-slipping device for shoes e0mprising a U-shaped calk, means for securing said 'calk to -the shoe sole, an upwardly yieldable spring metal ealk cleaner between the arms of said oalk5said cleanerhawdng'its rear end bent'toform a springcatch, and means-coasting with said spring catch to detachably "secure the cleaner in place,

In testimony whereof I-have hereunto set my hand in'the' presence ()ftWO subscribing witnesses.
